Dear R users,
I have two files of seasonal rainfall data (more than 10,000 rows each); here
the first 8 rows of each file are reported.

I have to load them as data frames, to merge them and sort them by
(Y_init,M_init,D_init,Code_Raingouge).
I wrote a short function where I first load the two files as data frames
df_1 <- read.csv(file="prec_all_19521201_19821201.csv", sep=",")
df_2 <- read.csv(file="prec_all_19821201_20111201.csv", sep=",")
then I merge them by
df_final <- merge(df_1, df_2, all=TRUE)
and finally I try to order df_final through
df_final <- df_final[order(Y_init, M_init, D_init, Code_Raingouge), ]
but this returns only the first row.
I read the manual carefully and I saw some examples, but I have not been able
to do this simple task.
I spent quite a long time and now I decided to ask the list.
Could please somebody help me to show me where the mistake is?
Thank you
Stefano
